Inverter power supply cannot do without aluminum electrolytic capacitor. The quality of electrolytic capacitor directly affects the stability and reliability of inverter power supply. If you want to improve the reliability of inverter power supply, the quality of electrolytic capacitor is very important. Lets take a look at the explanation of experts. in the design of power supply, efficiency and reliability are the first factors considered by designers, especially in the design of inverter power supply. The improvement of the reliability of inverter power supply is a relatively difficult task for novices
With the development of modern science and technology, flexible, wearable, foldable and intelligent electronic devices are the mainstream direction of development. Energy storage devices that provide energy for electronic products are also gradually developing in the direction of light, thin and tough. Flexible supercapacitor is a kind of energy storage device, which has the characteristics of high capacity, fast charging and discharging speed, safety and environmental protection. It has a broad application prospect in the emerging electronic intelligent equipment and other high-tech. Carbon fiber and carbon nanotube gauze, etc
Recently, the global launch of CSRs super capacitor energy storage modern tram and the signing activity for the first use of Ningbo were held at CSRs Ningbo industrial base in five towns of Yinzhou District. Ningbo has become the first city in the world to purchase new models and use them for public transport. A few days ago, Liu Qi, member of the Standing Committee of the provincial Party committee and Secretary of the municipal Party committee, met with Zheng Changhong, chairman of CSR Co., Ltd., who came to Ningbo to participate in the launch activities. Vice governor Xiong Jianping, deputy secretary of the municipal Party committee and Mayor Lu ziyue attended the meeting
AVX company of America has introduced lead-free RV series high-voltage, dual in-line stacked switching power supply capacitors, which can be used in power conversion and regulation, motor and motor driver, medical spectroscopy and other fields. The voltage of this series of products ranges from 1000V to 5000v, and the capacitance ranges from 100pfa to 15pfa. The RV series power electronic devices have low equivalent series resistance and inductance, small self leakage current, and can be used for
1. The installation position of the bolt aluminum electrolytic capacitor during the working period, the aluminum electrolytic capacitor will continue to flow leakage current, resulting in electrolysis. On the one hand, the oxygen produced by electrolysis will regenerate the insulation layer, but on the other hand, the released hydrogen will generate air pressure inside the capacitor. When the air pressure reaches a certain level, the safety valve on the cover plate will release the gas, so as to prevent the explosion of the capacitor due to the high air pressure during overload. In order to prevent electrolyte leakage during gas release, the terminal of capacitor (safety
Electrolytic capacitor service life (also defined as service life and working life) refers to the life that can be achieved when the failure rate of aluminum electrolytic capacitor does not exceed the specified value. The total failure or expected failure variable constitutes the end of service life. Depending on the circuit design, device failure caused by parameter variables does not necessarily mean equipment failure. This means that the actual life of aluminum electrolytic capacitor may be longer than the given service life. The data of service life come from industry experience and accelerated test
